CBO QSFP Active Optical Cable 5m 40Gbit/s Male-to-Male model 740-044967-BL

The CBO QSFP Active Optical Cable 5m 40Gbit/s Male-to-Male model 740-044967-BL is a factory-terminated, fixed-length active optical link designed for direct server, switch and storage interconnects. This 5‑metre BlueOptics cable integrates QSFP-to-QSFP connectors and active optics into a single assembly to deliver 40 Gbit/s full-duplex bandwidth with low latency and without separate pluggable transceivers. The cable is intended for short-reach high-speed connections in data centres and enterprise network racks where simplified installation and lower port power consumption are priorities.

Advantages

This Active Optical Cable provides a compact, pre-terminated solution that eliminates the need for separate transceivers and short fibre patch cords. By combining QSFP connectors and active optical hardware in a single 5 m assembly it reduces installation time and potential mismatch issues. The fixed-length fibre design ensures predictable link behaviour and low-latency performance suitable for high-bandwidth applications. As a factory-assembled cable, it offers reliable optical alignment and consistent signal integrity across installations.

Suitable for

• 40 Gbit/s links between QSFP-equipped switches and routers
• Server-to-switch high-speed uplinks in data centre racks
• Storage network interconnects requiring low latency and high throughput
• Short-reach connections in enterprise network cabinets and blade chassis

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 5 metres
• Data rate: 40 Gbit/s (full-duplex)
• Cable type: Active optical cable (factory-terminated)
• Typical use: Short-reach data centre and enterprise interconnects

How to use

Install the cable by inserting each QSFP male connector into the QSFP port of the corresponding devices while following standard ESD and hot-plug precautions for network equipment. Ensure the ports are compatible with QSFP Active Optical Cables and that link settings on the connected devices match the intended 40 Gbit/s operation. Route the cable to avoid tight bends and mechanical strain; secure with cable management hardware if required. No separate transceivers or additional fibre patching are needed.

Recommendations

Verify compatibility with the QSFP ports on both devices and consult device documentation for supported active optical cable types. Maintain bend radii within manufacturer guidelines and avoid repeated flexing near the connector ends to preserve optical performance. For optimal results in rack environments, manage the 5 m cable length to prevent stress on ports and ensure adequate airflow around network equipment.
